Additional Test (Part - 1) - Question 1

Although they may seem to be two very different issues, climate change and air pollution are closely interlinked. Consider the following statements in this regard:

1. Particulate matter that causes air pollution also reduces albedo in Polar Regions.

2. Aerosols act as both positive and negative climatic feedbacks.

Which of the above statements is/are incorrect?

Detailed Solution for Additional Test (Part - 1) - Question 1 PM- When it lands on ice and snow it darkens them slightly, leading to less sunlight being reflected back into space (reduced albedo), and contributing to global warming. Aerosols may be of either natural or anthropogenic origin and can influence climate in several ways

Additional Test (Part - 1) - Question 2

Which of the following are the main component gases of Green House Gas emission?

1. Carbon dioxide

2. Methane

3. Nitrogen

4. Nitrous oxide

Select the correct answer using the code given below:

Detailed Solution for Additional Test (Part - 1) - Question 2 The main component gases of GHG emissions are – Carbon dioxide Methane Chlorofluorocarbons Nitrous oxide Ozone

Additional Test (Part - 1) - Question 3

Which of the following gas is released by incomplete combustion of petrol and wood and it lowers the amount of oxygen if inhaled in human blood?

Detailed Solution for Additional Test (Part - 1) - Question 3 Carbon Monoxide (CO) It is a colourless, odourless gas that is produced by the incomplete burning of carbon-based fuels including petrol, diesel, and wood.

It is also produced from the combustion of natural and synthetic products such as cigarettes. It lowers the amount of oxygen that enters our blood. It can slow our reflexes and make us confused and sleepy.

Additional Test (Part - 1) - Question 4

Which of the following best represents the Greenhouse Gases (GHGs) in the descending order of their Green House Warming Potential for the time period of 100 years?

Detailed Solution for Additional Test (Part - 1) - Question 4 GreenHouse Warming Potential (100-year) Carbon Dioxide 1 Methane 21 Nitrous Oxide 310 Hydrofluorocarbons (HFCs) 140-11700 Perfluorocarbon (PFCs) 6500-9200 Sulphur Hexafluoride(SF6) 23900.

Additional Test (Part - 1) - Question 5

Match the following pairs: List I & List II

List I

A- Black Carbon

B- Brown Carbon

C- Blue Carbon

D- Green Carbon

List II

1. Stored in the form of aquatic biomass

2. Originates from the incomplete combustion of fossil fuels

3. Stored in the soil of natural ecosystems

4. Released by the combustion of organic matter

Select the correct answer using the code given below:

Detailed Solution for Additional Test (Part - 1) - Question 5 List I →List II

A. Black Carbon I → 2. Originates from the incomplete combustion of fossil fuels

B. Brown Carbon I → 4. Released by the combustion of organic matter

C. Blue Carbon → 1. Stored in the form of aquatic biomass

D. Green Carbon → 3. Stored in the soil of natural ecosystems

Additional Test (Part - 1) - Question 6

Consider the following statements:

1. The carbon footprint is a measure of human demand on the Earth’s ecosystems.

2. The carbon footprint tells the demand on the Earth that results from burning fossil fuels.

3. Earth Overshoot Day is calculated by the Global Footprint Network.

Which of the above statements is/are correct?

Detailed Solution for Additional Test (Part - 1) - Question 6

The “ecological footprint” is a measure of human demand on the Earth’s ecosystems.

 

 

Additional Test (Part - 1) - Question 7

Which of the following statements regarding Carbon Credits and Carbon Offsets is/are correct?

1. Carbon Offset represents the legal right to emit one ton of carbon or equivalent greenhouse gas.

2. Carbon Credit is generated by a reduction in emissions made by a voluntary project designed for that purpose.

Select the correct answer using the code given below:

Detailed Solution for Additional Test (Part - 1) - Question 7 A carbon credit is a tradable certificate or permits representing the right to emit one ton of carbon or carbon dioxide equivalent (tCO2e). Carbon offsets are credits for reductions in greenhouse gas emissions made at another location, such as wind farms which create renewable energy and reduce the need for fossil-fuel powered energy.

Additional Test (Part - 1) - Question 8

Which of the following is/are the parameters for defining water quality?

1. Turbidity

2. Chemical Oxygen Demand

3. Hardness due to presence of Arsenic, Cadmium and Chromium.

Select the correct answer using the code given below:

Detailed Solution for Additional Test (Part - 1) - Question 8 Hardness due to the presence of Arsenic, Cadmium and Chromium is not a parameter for defining water quality. DISSOLVED OXYGEN IS ALSO USED AS MEASURE OF QUALITY OF WATER.

Additional Test (Part - 1) - Question 9

With reference to extra-terrestrial causes of climate change, consider the following statements:

1. An increase in the number of sunspots leads to warmer and drier conditions on Earth.

2. As the orbital eccentricity of earth increases, summer days increase in both the hemispheres.

3. The axial tilt of Earth’s rotational axis controls the duration of seasons.

Which of the above statements is/are correct?

Detailed Solution for Additional Test (Part - 1) - Question 9 Increase in the number of sunspots leads to cooler and wetter weather on Earth.

Additional Test (Part - 1) - Question 10

Consider the following statements related to the Green-House effect:

1. Clouds are effective at absorbing infrared radiation and therefore exert a large greenhouse effect.

2. Warmer global temperature causes sea level to rise due to the thermal expansion of seawater.

3. Fluorinated gases are the greenhouse gases that do not occur naturally, but have been developed by man for industrial purposes.

Which of the above statements is/are correct?

Detailed Solution for Additional Test (Part - 1) - Question 10
  • The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.

  • Greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons (CFCs).

  • Clouds are effective at absorbing infrared radiation and therefore exert a large greenhouse effect.

  • Warmer global temperature causes sea level to rise due to the thermal expansion of seawater.

  • Fluorinated gases are the greenhouse gases that do not occur naturally, but have been developed by man for industrial purposes.
